jQuery enables the disabled button to prevent repeated submissions, layer.confirm determines that the button is locked to prevent repeated triggering events

<a class="btn btn-warning" id="releaseBtn" onclick="ShipPlanManager.release()">
 <i class="fa fa-pencil"></i> 计划下发
</a>

/**
 * 计划下发

     var ids = "";

         ids = ids + data[i].id + ",";
     }
     ids = ids.substring(0, ids.length - 1);
